Abstract: An array substrate, a display panel, and a manufacturing method of the array substrate are provided, including a thin film transistor layer, a passivation layer, and a pixel electrode layer which are sequentially disposed on one above another. The passivation layer is provided with a first via hole and a second via hole staggered from each other. The pixel electrode layer includes a pixel electrode connected to a first conductive layer through the first via hole and the second via hole. Therefore, a problem of grayscale dark spots caused by the pixel electrode being broken at a connection point with the first conductive layer is avoided.

Abstract: The present disclosure discloses a display panel and a display device. According to the display panel, a fracture is provided on each gate signal line, so that the each gate signal line does not transversely extend through a display area. In this way, an abnormal invalid gate circuit area in a range of the display area at a left part below a dashed line formed by connecting the plurality of the fractures does not affect transmission of a gate signal, thereby reducing a reject ratio of products.
